Application December 16, 1954, Serial No. 475,602

Claims. (Cl. 118-3) This invention relates to glue tipping devices and particularly to an assembly of glue tipping units which are adapted to be quickly and easily adjusted to place glue dots in a plurality of predetermined places on sheets of paper in connection with the preparation of manifold books, snap out carbonized sets, Christmas cards, calendars, sample books, etc.

The use of glue tipping machines is old and We are particularly familiar with the Glue Tipping Machine described and disclosed in the co-pending application of Charles F. Forslund, Jr., Serial No. 288,651, filed May 19, 1952, now U. S. Patent No. 2,753,836, for a Glue Tipping Machine. That device is particularly adaptable for use in small printing shops for use in connection with the preparation of manifold books and snap-out carbonized sets. Such items are customarily formed by collation which, as is well known to those skilled in the art, is a gathering together of a number of various sheets in predetermined combinations for binding. In the past the binding of such sets of collated material has been confined to relatively large size equipment which is impractical for use in small printing shops, but the device disclosed and claimed in said Forslund application provides a glue tipping machine suitable for use in small shops which requires a minimum of experience on the part of the individual operating the machine and which also requires the minimum by Way of upkeep and repair.

The machine described in the said Forslund application, however, is provided with only a single elongated glue fountain provided with suitable nozzles for applying glue dots in a single line. chine, the product has been run and tipped in a single row; that is, the dots of glue were in a straight line only.

We propose to provide a device in which the dots of glue may be placed in any desired pattern, including a straight line, at any point on the surface of the papers to be glued together.

It is an object of this invention to provide a device of thi kind which is simple and inexpensive to manufacture, which is easy to operate and which consists of no complex or hard-to-handle parts.

Other objects and advantages of this invention will appear from the following specification taken in conjunction with the accompanying drawings in which:

Figure l is a plan view of a device incorporating our invention;

Figure 2 is a cross sectional detail taken along the line 22 of Figure 1;

Figure 3 is a side view of the device illustrated in Figure 1;

Figure 4 is an enlarged cross section taken along the line 4-4 of Figure 1;

Figure 5 is a cross sectional view taken along the line 55 of Figure l; and' Figure 6 is a view taken along the lines 6 -6 of Figure 4.

At the outset let it be made clear that our multiple foun- In the use of such a matain device is adapted to be used in conjunction with a glue tipping machine of the type disclosed in the aforementioned Forslund application which, it will be noted, discloses means for actuating a glue fountain into and out of engagement with a stack of papers to which glue is tobe applied. Specifically the device comprises two pairs of swinging arms 10 and 11 which, as illustrated in Figure 3, are pivotally connected with and mounted upon driving mechanism 12 and pillow-block 13 so that a parallelogram type motion is obtained and further so that our assembly 14 will at all times be horizontal with respect to the material being worked upon. Therefore, when the arms 10 and 11 are caused to be raised and lowered .as described in said Forslund application, our multi-tipping device will likewise be raised and lowered.

As illustrated particularly in Figures 1 and 3, our device is supported in the pillow-blocks 13. The pillowblocks 13 are bored to accommodate reciprocablymounted pins 16 to the lower ends of which our assembly 14 is secured.

Our device consists generally of an elongated member 17 whose ends are suitably secured to the pins 16 in a suitable manner and which are provided with elongated slots 18. The member 17 serves as a mounting for a plurality of adjustable slide members 19 which are provided with central orifices 21 and with similar elongated slots 22. The orifices 21 are aligned with the slots 18 in the member 17 and, by virtue of the construction illustrated in Figure 4, they are adapted to be maintained upon the member 17 either by the glue pot assemblies 23 or the securing assembly 24.

Generally speaking, the glue fountains 23 consist of a storage pot receptacle 25 having an upper removable cover 26 and a lower integrally formed non-removable base and nipple portion 27. The nipple portion 27 is exteriorly threaded as indicated at 28. His drilled and threaded to accommodate a nozzle 29 which is provided with an orifice at its lower end and which is adapted to accommodate a so-called free floating vertical rod 30 which acts as a valve closure member and which, by gravity, closes the orifice by engaging the side walls of the orifice. However, the free floating member normally extends downwardly below the lower level of the orifice in the nozzle 29 whereby' when it engages another object, as for example a sheet of paper, the free floating member 30 will be urged upwardly whereby the orifice will be opened and a quantity of glue which is stored within the fountain 23 will be deposited upon the paper. When the nozzle 29 is raised to a position in which the free floating member 30 no longer engages the paper, the member 30 will serve to close the orificeand prevent the further flow of glue therethrough;

The threaded portion 28 is adapted to cooperate with a threaded member 31 which, as shown in Figures 2 and 6, takes the form of a hexagonal nut. Thus when the foun tain 23 is positioned on the member 17 in such a manner that it extends through one of the elongated slots 18, its threaded portion 28 may engage the similarly threaded portion of the hexagonal nut 31. In this manner the glue fountain is retained in a particular position with respect to one of the elongated slots 18 or 22.

However, as illustrated in Figure 4, the same unit may be used to secure the members 19 to the member 17. In this instance, the elongated threaded projection27 will, as illustrated in Figure 4, extend downwardly through the orifice 21 and the cooperating slots 18 and, by means of the threaded member 31, serve to secure the assembly to gether.

Moreover, when it is desired that one of the slides 19 be fastened to the member 17 in such a manner that the use of a glue pot is not called for, as, for example, when it is not desired that a'spot of glue be deposited at that point,

a simple nut and bolt assembly may be used as illush'ated at the extreme right hand position of Figure 4.

The same nut 31 may be used but the threaded member 32 may consist of a conventional threaded bolt which is provided with an enlarged head 33. o

Operation of thedevice may briefly be described as follows: The mechanism which causes the arms 'and 11 to be raised or lowered must of course be in operating condition. The operator then ascertains that the shafts 16 are free to reciprocate within the bores in the pillowblocks 13 in such a manner that the assembly 14 may be raised and lowered. The slidemembers 19 are then positioned on the member 17 either by the use of a glue pot 23 or by the use of the nut and bolt assembly 24 shown in the extreme right hand portion of Figure 4. Glue pots are positioned at predetermineddesired points along tne members 17 and 19 byipositioning them at selected points along the slots 18 and 22 as generally illustrated in Figure 1. The machine is then caused to operate and glue dots will be deposited by the glue fountains 23 in the desired pattern.

It is obvious that the use of our invention permits greater and more flexible utilization of a glue tipping machine in that it provides a quickly and easily arrangeable combination of glue tippers. This will permit the placing of glue dots practically anywhere within the limits of an area which may be defined by the dotted line area indicated in Figure 1. The advantages of this construction are obvious. For example, Where small forms such as hotel check-in tickets, private club meal and bar chips, route lists and other snap-outs have been run and tipped in a single row, they may now be printed in three or four rows and tipped in one operation. Working with larger sheets of both the printed form and carbon paper decreases handling and with the three or four time increase in production rates on the actual tipping, job costs are reduced tremendously. Moreover, irregular tipping patternsare easily set up on our device. This applies particularly to tip-on jobs, that is, Christmas cards, calendars, sample books with cards tipped to pages, and many other special jobs which are now customarily done by hand.
